Titanium Hex Bolts Frequently Asked Questions (FAQ)
Titanium hex bolts frequently asked questions (FAQ)
Q1: What are the disadvantages of titanium bolts?
Titanium is relatively expensive and has lower shear toughness than grade 12.9 high-strength steel, so it is not recommended for high-shear or impact-load connections.
Q2: Are titanium bolts good to use?
Yes. They are lightweight, corrosion-resistant, and require no coating, making them suitable for most structural connections. Just install with the correct torque and use anti-seize compound.
Q3: Should I apply anti-seize during installation?
Yes. Titanium-to-titanium assemblies can cold weld. Use MoS₂ grease or a titanium-specific anti-seize to ensure smooth removal and prevent galling.
Q4: Are titanium bolts stronger than steel bolts?
Grade 5 titanium has higher tensile strength than grade 8.8 carbon steel and is slightly lower than grade 12.9, but it weighs nearly 50% less—offering the best balance between strength and weight.
Q5: Can titanium bolts replace stainless steel?
Yes. In high-corrosion environments such as salt spray or seawater, titanium outperforms stainless steel in durability, offering a longer lifespan and lower maintenance costs.
Q6: Do I need material reports or certifications?
All titanium bolts can be supplied with EN 10204 3.1 material certificates, and we support AS9100D / NACE MR0175 compliance for project requirements.
Q7: Can you make non-standard sizes?
Yes. We can machine to drawing, cut non-standard lengths, provide small-batch samples, and supply complete kits—contact us for customization.
